Title: Vacuum generating valve
Inventor: HIEI SHIYOUKI
IPC: B25J15/06
Filed: 1979-09-17
Abstract: PURPOSE:To provide a vacuum generating valve, in which a valve element for permitting and inhibiting flow of compressed air introduced from an outlet port is formed with a means for making the sectional area of an outlet passage located between the inlet port and an outlet port larger at the time when air flow is inhibited than at the time when the air flow is permitted and said means is formed integrally with said valve element, whereby it is enabled to simplify piping arrangement and to make the entire structure compact. CONSTITUTION:In the state of apparatus shown in the drawing, electromagnetic valve 11 is in its de-energized condition. In this state, if compressed air is introduced from inlet port 3, it is passed through bore 2, thru-hole 17, throttle 15 and tapered bore 16 and discharged to the atmosphere via outlet port 9. Here, since velocity of compressed air flow is increased at throttle 15, air in work chamber 28 of suction disk 26 communicated to the throttle 15 via valve chamber 10, passage 4, suction port 5 and piping 27 is drawn out to the atmosphere by the function of Venturi effect, so that inside of the work chamber 28 is evacuated. By the vacuum generated in chamber 28, work 29 is attracted to suction disk 26.

Title: Outline slip crystal vibrator
Inventor: MOCHIZUKI YUUZOU
IPC: H03H9/19
Filed: 1978-09-27
Abstract: PURPOSE:To improve a frequency temperature characteristic by inclining both longer sides at several degrees in the thickness direction. CONSTITUTION:In crystal rotary Y plate 31 having a cut face which rotates at approximately 50 deg. from the z axis of the crystal axis, the vibration displacement direction is parallel with the X axis and acts to the side face to generate combination with other vibrations in the outline slip vibration mode having a thin-plate from which is long in the X axis direction and short in the Z axis direction. Therefore, though the ternary temperature characteristic is given fundametally, the secondary temperature characteristic is given. Consequently, the ternary temperature characteristic appears by providing a free face which does not act to the side face. Then, a crystal vibrator of an outline slip vibration mode of frequency band 100kHz- 1MHz having the ternary temperature characteristic is obtained by inclining both longer sides at 5 deg. in the direction of thickness t.

Filed: 1989-05-15
Abstract: PURPOSE:To prevent missed search by compensating the phases of respective receiving signals so that the center of phase synthesis comes to a missing search part and subsequently performing the phase synthesis of the respective receiving signals. CONSTITUTION:When an inputted control signal shows 'phase non- compensation', a phase compensating circuit 7 outputs the output of the corresponding memory circuit 6 to a phase synthesizing circuit 8 as it is but, when the control signal shows 'phase compensation', said circuit 7 performs the predetermined phase compensation with respect to the output of the corresponding memory circuit 6 to output the output of the memory circuit 6 to the phase synthesizing circuit 8. As a result, when missed search is generated, the center of the beam formed by the phase synthesis due to the phase synthesizing circuit 8 is present at the missed search part and azimuth resolving power is formed into DELTAy at a target distance (r). By this method, a desired image free from missed search is displayed on a display device 9.

Abstract: PURPOSE:To make production easy by providing an impedance where an eddy current is generated in accordance with responding operations of a diaphragm and a flat spring due to the variance of air pressure and the impedance is changed, and amplifying and calculating the output voltage as one element of a bridge circuit to obtain a barometric value. CONSTITUTION:In the state an impedance means 9 is attached to a baseplate 1 and is supported, a conductor and a diaphragm 2 are approximately coaxial, and a prescribed length do is formed between the impedance means 9 and the other end 8 of a flat spring 4. When the air pressure is changed from a maximum measured high air pressure to a lower air pressure, the pulling-up force of the flat spring 4 surpasses the contracting force of the diaphragm 2, and the flat spring 4 is displaced in the direction of an arrow Q, and the length do is changed. Since an impedance Z2 is changed in accordance with this change, the output voltage V is increased in proportion to this change. This output voltage V is taken out and is subjected to amplification and operation processings and is subjected to analog-digital conversion, and a barometric value is displayed digitally. The flat spring 4 is so displaced that the length do is reduced to shortest at a minimum measured air pressure.
